Systems and methods for activity coordination in multi-radio terminals

An activity coordination method for a wireless communication device comprising a plurality of co-located radio modules, comprising:

• providing a first radio module for performing wireless transceiving in compliance with a first communication protocol and according to a plurality of first traffic patterns which each indicates allocations of a plurality of first slots for a plurality of forthcoming transmitting or receiving operations, respectively;
• providing a second radio module for performing wireless transceiving in compliance with a second communication protocol;
• determining, by the second radio module, an indicator indicating at least one of a plurality of second traffic patterns which each indicates allocations of a plurality of second slots for a plurality of forthcoming transmitting or receiving operations, respectively,
• wherein one or more allocations of the second slots are selectively determined by the second radio module according to the first traffic patterns;
• and
• transmitting, by the second radio module, the indicator to a peer communication device, so that the peer communication device performs transmitting or receiving operations to and from the second radio module according to the at least one of the second traffic patterns indicated by the indicator,
• wherein one or more allocations of the second slots are canceled by the second radio module when the receiving operations in the corresponding second slots are estimated to be interfered by the transmitting operations of the first radio module, and wherein one or more allocations of the second slots are canceled by the second radio module when data transmissions in the corresponding second slots are estimated to be interfering with the receiving operations of the first radio module.
